Re: [Gwt-openlayers-users] GWT + Openlayers - WFSProtocol - WFS version 1.1.0 does not work

[Paweł P. <ppa...@gm...>]

Hi!

I have made some mistake in my code, and now everything seems to be working
great. I add new geometry to the database using savestrategy. I used version
1.1.0 in WFSProtocolOptions.

Mikael my code in JS looks like this:

        var saveStrategy = new OpenLayers.Strategy.Save();

	   var  wfsproba = new OpenLayers.Layer.Vector("Editable Features", {
        strategies: [new OpenLayers.Strategy.BBOX(),savestrategy],
        projection: new OpenLayers.Projection("EPSG:4326"),
	   styleMap: wfs_style,
        protocol: new OpenLayers.Protocol.WFS({
            version: "1.1.0",
            url: "http://localhost:8080/geoserver/wfs",
            featureNS :  "http://www.openplans.org/topp",
            featureType: "tasmania_roads",
        })
    });


The most important thing is that you add *projection *section in the
definition, as I did. Please write to me if it works in your case...

BTW I think you should add savestrategy class to the repository, what do you
think about that??
Now I am going to figure it out how to delete, and modify feature... Do you
know if any of this were implemented in GWT-OL?? I suppose that it was
not...
